Sea surface temperatures in the North Atlantic have risen dramatically in recent weeks, to as much as 0.5 degrees Celsius warmer than the previous record—and over 1 degree C warmer than average temperatures from 1982 to 2011.
The reason for the unusually toasty waters isn’t entirely clear. Some climatologists attribute part of the rise to an El Niño ocean circulation pattern this year, replacing the La Niña pattern that had been suppressing temperatures. Other factors may include a decline in atmospheric dust from the Sahara, and atmospheric circulation patterns that are allowing warm surface water to stay in place longer.
The warmer temperatures aren’t just limited to the North Atlantic, however—for the past three months, global average sea surface temperatures have also been reaching new highs. Casey Crownhart, a climate reporter at MIT Technology Review, joins Ira to talk about the warming trend, and other stories from the week in science, including accusations of body part sales from the Harvard Medical School morgue, studies of the economics of heat pumps, and a lawsuit brought by youth in Montana over global warming.
The Best Summer Books, According To Two Science Writers
Summer is one of the best times to crack open a book and read the hours away, according to Jaime Green and Annalee Newitz. The two science writers are voracious readers, and they’ve compiled a list of their summer reading recommendations for Science Friday listeners. Green and Newitz join Ira from New Britain, Connecticut and San Francisco, California respectively, to discuss their favorite nonfiction and fiction books for the summer, and take questions from listeners.
